f39650de68 kernel.h: split out panic and oops helpers
kernel.h is being used as a dump for all kinds of stuff for a long time.
Here is the attempt to start cleaning it up by splitting out panic and
oops helpers.

There are several purposes of doing this:
- dropping dependency in bug.h
- dropping a loop by moving out panic_notifier.h
- unload kernel.h from something which has its own domain

At the same time convert users tree-wide to use new headers, although for
the time being include new header back to kernel.h to avoid twisted
indirected includes for existing users.

[akpm@linux-foundation.org: thread_info.h needs limits.h]

391e2415e9 misc/pvpanic: Make some symbols static
Fix sparse warnings:

drivers/misc/pvpanic/pvpanic.c:28:18: warning:
 symbol 'pvpanic_list' was not declared. Should it be static?
drivers/misc/pvpanic/pvpanic.c:29:12: warning:
 symbol 'pvpanic_lock' was not declared. Should it be static?

b3c0f87746 misc/pvpanic: probe multiple instances
Create the mecahism that allows multiple pvpanic instances to call
pvpanic_probe and receive panic events. A global list will retain all the
mapped addresses where to write panic events.

6861d27cf5 misc/pvpanic: split-up generic and platform dependent code
Split-up generic and platform dependent code in order to be able to re-use
generic event handling code in pvpanic PCI device driver in the next patches.

The code from pvpanic.c was split in two new files:
- pvpanic.c: generic code that handles pvpanic events
- pvpanic-mmio.c: platform/bus dependent code
